Yes. Yes! A thousand times YES.

Or better:

Two solutions: stop using a buggy shell or use {A..Z} which doesn't have the problem. Well, a third would be to have bash expand globs on <Tab> like Zsh can[1], but I don't know how to do that.

[1]`rm a*<Tab>` becomes `rm afile adir` and so on.

That has a different problem: Unlike the glob pattern [A-Z], the braces expand to every letter from A to Z, even if some of them don't match:

$ echo [A-D]*
Desktop Documents Downloads
$ echo {A..D}*
A* B* C* Desktop Documents Downloads

> have bash expand globs on <Tab> like Zsh can[1]

The readline command for this in Bash is glob-expand-word (C-x *).
